YC Demo Day Winter 2013 Batch – Quick Reference Index

Today is Y Combinator Demo Day, and I’ve compiled a list of Y Combinator startups from the current batch who have officially launched (27 of 47) and ranked them using the same methodology as this month’s YC Index. It is extremely early days for these companies, this can give you a sense of who is getting attention and seeing early growth and we will use this as a benchmark for them in the index going forward. I will update this post as new companies are launched throughout the day.

The companies highlighted in orange would have made it into the top 100 of the Y Combinator Index released for March. All companies will be included in the April index.

I post this with the caveat that web traffic rarely tells the full story for any company. We have done our best to also factor in Facebook monthly active users and mobile app rankings, but for enterprise and developer tools companies the amount of website traffic they receive can be disproportionately low compared to how much money they make.
